ZIF Connectors
Figure 18.  ZIF Connector Release
NOTICE: ZIF connectors are fragile. To avoid breaking the connectors, 
touch them carefully. Do not apply too much pressure to the movable part 
of the connector when opening or closing it.
Some of the computer’s interface connectors are ZIF connectors. These connectors 
are not removable; they must be released (see Figure 17) to disconnect a cable from 
them.
